Sure, lets do it. BWI is good. When I say trackable threat, it has to be showing up on the 144hr (6 days) or less GFS and has to have at least SOME support from other guidance. I have no question there will be plenty of fictional storms, cold air, and epic pattern changes at that time on the 216+hour.
I maintain there is a very good chance that I-95 shuts out the rest of the winter. A dusting-an inch aside.
An epic win would be a 5+ inch snowstorm at this point that brought the area to AVERAGE.
